Peter Maydell 032333eba7 hw/display/xlnx_dp: Don't abort for unsupported graphics formats 
If the guest writes an invalid or unsupported value to the
AV_BUF_FORMAT register, currently we abort().  Instead, log this as
either a guest error or an unimplemented error and continue.

The existing code treats DP_NL_VID_CB_Y0_CR_Y1 as x8b8g8r8
via a "case 0" that does not use the enum constant name for some
reason; we leave that alone beyond adding a comment about the
weird code.

Documentation of this register seems to be at:
https://docs.amd.com/r/en-US/ug1087-zynq-ultrascale-registers/AV_BUF_FORMAT-DISPLAY_PORT-Register
